In fiber concretes, composites are used as a new technology in the construction industry. Among the new materials that have a special place in construction are concrete additives and reinforcing fibers. These materials improve the desired properties of concrete, such as its strength, and in some cases, by reducing the weight of concrete, it provides very light materials to building engineers. A new type of concrete entered the industrial field. The tensile and shear strength of fiber concrete is higher than normal concrete.
